Chip Kelly hasn't been shy about admitting the disadvantage his teams were faced with. The often brash head coach did something a lot of high-profile coaches wouldn't do. He admitted that his system might not always work against the mighty SEC without the proper personnel. One way to gauge Kelly's shift in philosophy is by looking at the defensive linemen the Ducks brought in this past recruiting cycle: 6-foot-8, 297-pound Arik Armstead; 6-foot-7, 240-pound DeForest Buckner; 6-foot-4, 260-pound Alex Balducci; 6-foot-6, 230-pound Cody Carriger and 6-foot-7, 275-pound Stetson Bair. After years of having smaller and quicker defensive linemen, the Ducks look to be building a front wall that can match the size and power of the NFL lineman factories in the Southeast.
